Unlike most other rapid transit systems, BART lines historically were not primarily referred by color names (although the colors used on maps have been constant since 1980) or other shorthand designations. The eastern segment of the Yellow Line (between Antioch and the transfer platform east of Pittsburg/Bay Point) uses different rolling stock and is separated from the rest of the line.

All stations are served during all service hours. All five services run every day until 9 pm only three services operate evenings after 9 pm. All of the heavy rail services run through Oakland, and all but the Orange Line cross the bay through the Transbay Tube to San Francisco. BART operates five named heavy rail services plus one separate automated guideway line. The system has 50 stations: 22 in Alameda County, 12 in Contra Costa County, 8 in San Francisco, 6 in San Mateo County, and 2 in Santa Clara County.

Services īART serves large portions of its three member counties – San Francisco, Alameda, and Contra Costa – as well as smaller portions of San Mateo County and Santa Clara counties. The system has been extended several times, most recently in 2020, when Milpitas and Berryessa/North San José stations opened as part of the under construction Silicon Valley BART extension in partnership with the Santa Clara Valley Transportation Authority (VTA). The initial system opened in stages from 1972 to 1974. With an average of 146,500 weekday passengers as of the fourth quarter of 2022 and 41,286,400 annual passengers in 2022, BART is the fifth-busiest heavy rail rapid transit system in the United States.īART is operated by the San Francisco Bay Area Rapid Transit District which formed in 1957. BART serves 50 stations along six routes and 131 miles (211 kilometers) of track, including a 9-mile (14 km) spur line running to Antioch, which uses diesel multiple-unit vehicles, and a 3-mile (4.8 km) automated guideway transit line serving the Oakland International Airport.
